The fallopian tubes were examined for the presence of low-resistance arterial flow.<\/jats:p>\n                  <jats:p>Results: Of the 100 cases, 19 women had ectopic pregnancies. It was observed that all cases of ectopic pregnancies had a typical eccentric leash of vessels on color Doppler that showed a low resistance placental type of flow on spectral Doppler.<\/jats:p>\n                  <jats:p>Conclusion: We propose a new reliable sign of ectopic pregnancy called the leash sign. This sign has a sensitivity of 100% and specificity of 99%, a positive predictive value of 95% and negative predictive value of 100%, thus helping in the diagnosis of early ectopic pregnancy, and resulting in earlier treatment with reduced morbidity and mortality.<\/jats:p>","DOI":"10.1080\/02841850600644782","type":"journal-article","created":{"date-parts":[[2006,5,31]],"date-time":"2006-05-31T21:49:54Z","timestamp":1149112194000},"page":"529-535","source":"Crossref","is-referenced-by-count":13,"title":["Ectopic pregnancy \u2013 the leash sign. a new sign on transvaginal Doppler ultrasound"],"prefix":"10.1177","volume":"47","author":[{"given":"R.
